XM Installation
Requirements This section describes wire, power, grounding, and terminating resistor
requirements for an XM
system.
Wiring Requirements
Use solid or stranded wire. All wiring must meet the following specifications:
• 2.1…0.3 mm
2
(14…22 AWG) copper conductors without pretreatment;
8.4 mm
2
(8 AWG) required for grounding the DIN rail for
electromagnetic interference (EMI) purposes
• Recommended strip length 8 mm (0.31 in.)
• Minimum insulation rating of 300V
• Soldering the conductor is forbidden
• Wire ferrules can be used with stranded conductors; copper ferrules
recommended
Power Requirements
Before installing your module, calculate the power requirements of all modules
interconnected via their side connectors. The total current draw through the side
ATTENTION: The installation requirements may be different for different
XM modules. The following requirements apply only to the 1440-SDM02-
01RA module. Refer to the user manual for the specific XM module for its
requirements.
The XM-124 module is designed so that it may be used to replace an XM-
120 or XM-121 module, revisions D01 or later. If an earlier revision of an
XM-120/XM-121 module is being replaced, wiring changes may be
required. Refer to the XM-120/XM-121 User Manual for details.
If replacing an XM-120/XM-121 module and the XM-120/X-121’s onboard
relay is being used, be sure that the relay requirements and wiring solution
are considered, as differences exist between the onboard relays of the
XM-120/XM-121 and the XM-124 module.
ATTENTION: The XM-124 module requires a minimum clearance of 25 mm
(1 in.) from the top and bottom of the device.
